Officials decided to axe the final day of the three-day music and arts bash as "dangerous weather conditions" were forecast for City Park, and they later shared photos of the soaked grounds on social media, reported Rolling Stone magazine.
Alongside the images, a representative wrote, "The decision to cancel today was based on the safety of the Tribe - fans, artists, staff, vendors, and all involved."
The Zac Brown Band, Slightly Stoopid, The Cult and Eric Prydz had also been due to perform.
